Answer:
Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature.
Removing energy (cooling) atoms and molecules decreases their motion, resulting in a decrease in temperature.
Energy can be added or removed from a substance through a process called conduction.
In conduction, faster-moving molecules contact slower-moving molecules and transfer energy to them.
During conduction the slower-moving molecules speed up and the faster-moving molecules slow down.
Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance.
Heat is the transfer of energy from a substance at a higher temperature to a substance at a lower temperature.
Some materials are better conductors of heat than others.
Explanation:
Objective
Students will be able to describe and draw a model, on the molecular level, showing how energy is transferred from one substance to another through conduction.
